PICKEB. FOR COTTON LINT.

Specification of Letters Patent.

Patented Jan. 5, 1915.

Application filed May 28, 1913. Serial No. 770,357.

To all whom it may concern:

Be it known that I, IVAR MEURLING, a subject of the Crown of Sweden, buthav ng announced my intention of becom ng a citizen of the United Statesof Amerlca, and a resident of Brooklyn, county of Kings, and State ofNew York, have invented certam new and useful Improvements in Pickersfor Cotton Lint, of which the followmg 1s a specification, referencebeing had to the accompanying drawings, forming a part thereof.

This invention relates to an improvement in pickers for cotton lint.

The object of the invention is to provlde a picker for seeded cottonwithout heaters by utilizing an air blast to separate the fibers.

I will describe my invention in the following specification and pointout the novel features thereof in the appended claims.

In the accompanying drawings; Flgure 1 is a sectional side elevation ofan illustrative embodiment of the invention. Fig. 2 is a fragmentaryvertical section, on an en larged scale, of the air blast mouth pieceand adjacent feeding mechanism.

As illustrated in the drawings the invention is applied to a standardpicker of well known construction comprising a pair of side frames 10 atthe one end of which a horizontal feed apron 12 is mounted on rollers14. The seeded cotton lint 15 is carried by said apron to a feed roll 16which cooperates with an adjustable hinged plate 18. This plate 18 actsupon an evener 20, the details of which are not shown as this forms nopart of my invention. The lint passes between the roll 16 and plate 18to the feed rolls 21, 22, from whence it passes into the path of the airblast by which it is separated and also freed from dirt.

23 is a fixed plate the upper edge of which is close to the surface ofthe roll 21 and is provided for the purpose of preventing the lint whichis blown against roll 21 from sticking to it.

The air blast is supplied by a fan or blower 24 mounted on a bridge 26located and clamped between the extensions 27 of the side frames 10. Theblower is driven by a belt 23 passing over a pulley 25 on a countershaft 29, said countershaft also driving a belt 31 which drives theshaft 35. The air from the blower passes through a pipe 28 connectedtherewith and provided at its lower end with a discharge nozzle or mouthpiece 30. The air blast is discharged from the mouthpiece 30 in front ofthe feed rolls 21, 22 and against a deflecting plate 82. The latter ishinged and adjusted by means of a screw 3 to regulate and direct the airblast.

The cotton is blown apart and conveyed by the air blast under aremovable hood 34 which is located above a screen 36, the latter formingthe top of an air tight dust box 38. At the bottom of the dust box 38 isa rotary valve 39, which may be rotated to allow the dirt and drosswhich collects in the box 38 to drop out. The rotary valve prevents theescape of air from the dust box when dirt is being removed therefrom.The air current generated by the fan strikes the cotton throwing thelatter against and dragging it over the curved screen 36. The dust anddirt will pass through the screen into the dust chamber, and from thereit will be deposited on the floor beneath the picker by the rotary valveat the bottom of the dust chamber. The cotton is then blown to anenlarged chamber 40 at the entrance to which is a grid 42 over which thecotton passes. Then the cotton comes under the influence of the pickersuction fan 44 which communicates with the rotary condenser screens 45and 46, and by the suction of said fan the cotton is drawn onto saidcondenser screens. From the condenser screens the cotton lint passesthrough various sets of feed rolls 48, 49 and 50 to the lap rolls 52where it is rolled up in the form of a lap 54.

By the construction above set forth it will be noted that the cottonlint fibers are thoroughly separated by the air blast but are notinjured as is the case with the customary heaters and consequently thefibers are not broken. The fire risk is reduced to a minimum and thelaps are cleaner and the yarn is stronger as a result of the operationof the device.

What I claim is:

1. A. lint cotton picker, comprising a screen, an air blast, means forfeeding the cotton into the path of said blast whereby the former isblown over said screen, means for adjusting the direction of said blast,a dust chamber below said screen, a rotary valve at the bottom of saidchamber, in

' combination with a receiving chamber pro-.

vided with rotary condenser screens, and means for forming the lint intoa lap roll.

2. A lint cotton picker, comprising a shield, a screen below saidshield,-a blower,

means for delivering a blast of air between S 2Lld*'Sl11'eld' andscreen, means for feeding:

cotton lint into the path of the air blast,

means for regulating and deflecting said blast, a dust collectingchamber below said screen; a rotary yalve" in" the bottom of said:chamber, and means for condensing the lint'ajndr formingfit'j into alap.

3. A lint cotton picker, comprising a frame,- a" shield conve'Xed,downwardly, a screen substantially parallel t'o said shield and formingthe top of a dust chamber, a fan mounted on said frame, means for conveying'fa blast of'air from said: fan to the spaee' beti'v'een saidshield and screen, vad'- ju'sta-ble means for deflecting and regulatingthe discharge of said air blast, means for feeding lint into the path ofsaid air blast, and means for condensing the lint and forming it into alap.

4;. A lintcotton picker, comprising a shield, a screen forming an airpassage with said shield, means for supplying a; blast of air underpressure at the entrance of said passage, a'h-inged plate for deflectingthe current of air, means for adjusting said plate, means for feedinglint to the air passage, and means for condensing the lint after it isdischarged from said passage.

In Witnesswhereof, I have-hereunto set my han'd this' 27 day of May inthe year 1913.

IVAR MEURLING.
